Each week, we highlight a selection of the most interesting, exciting, and unique new iPhone, iPad, and iPod touch titles released on the App Store. Glossy action affairs lead the week’s offerings, with sci-fi dungeon crawler Echo Prime and free-to-play zombie blaster Dead Trigger 2 debuting in the App Store. Also particularly intriguing this week are Even Up and Combat Monsters, with already-released brawler Combo Crew receiving a huge update in the form of playable Street Fighter characters.

Button-mashing brawlers make for a great time when you've got real buttons to mash, but they don't always translate so well to iOS touch screens. Rather than attempt to shoehorn all of the intense fighting action into a traditional arcade-style control scheme, indie studio The Game Bakers concocted a fresh touch-centric battle system for its quirky new face-pummeling fighter. Combo Crew's fast-paced fisticuffs and streamlined combo system hinges on simple swipe controls that are far more satisfying to wield than you'd expect from an iOS beat-em-up.
